Hi koyoyo,
frm wat i understand, u want to hold ur AD on a sat rite? i was like u initially n i kena scolding frm d shifu, true enuff, luckily he gave me 10 dates as i open my options to fri, sat n sun, if not, i'll b in ur shoes now. it's juz based on my experience n my personal opinion, no offence:
1. postpone ur AD
2. bring forward ur AD
3. hold ur AD and banquet on different days
4. widen ur choice of dates, as 11 oct n 18 oct is very popular
for d same reason dat i couldnt get for 11 oct n 18 oct, i've chosen a fri, 17 oct...hope it helps in ur decision-making
